The 1S 3.7V 300 mAh Dual Sky 25C LiPo batteries are designed for use with small scale RC helicopters such as Blade mCPX and are also compatible with other similar models such as WLtoys v922 or Turnigy FBL100 and others. These batteries are intended to be used as a replacement of the original batteries and supposedly they should be providing higher capacity for longer flight time as well as higher discharge rate for maximum performance during flight with the RC model, but can they deliver on what they claim…

We have started the tests with a 1C discharge rate (0.3A) for the 1S 3.7V 300 mAh Dual Sky 25C LiPo battery and we’ve managed to get just 269 mAh as a maximum capacity. This means that even at 1C discharge rate these batteries are not able to deliver their rated capacity of 300 mAh and that is not a good start at all. Furthermore, increasing the constant current load we saw that the batteries manage to handle well up to 10C discharge rate as a maximum and they fail at 15C, so we did not continue increasing the load further as it was pointless. Dual Sky rates these as 25C constant and 50C burst discharge rate, but they should be more like 10C constant and 15C burst and more like 250 mAh actual capacity. In short, we are disappointed by the performance that these batteries have shown in our tests.
